I feel confident in saying that NWN2 is one of my least favorite games of all time.
However, I will admit that the combat was alright. The character creation was good, as well. Everything else was drudgery, (seemingly) half-finished and slapdash.

They made NPC-shepherding into a science during one part of the main quest. It takes place in a bland, characterless dungeon. Emblematic of the NWN2 experience.
